Engine Block Heater: Description and Operation
ENGINE BLOCK HEATER 5.9L DIESEL
DESCRIPTION
WARNING: DO NOT OPERATE ENGINE UNLESS BLOCK HEATER CORD HAS BEEN DISCONNECTED FROM POWER SOURCE
AND SECURED IN PLACE. THE POWER CORD MUST BE SECURED IN ITS RETAINING CLIPS AND ROUTED AWAY FROM
EXHAUST MANIFOLDS AND MOVING PARTS.
An optional engine block heater is available on all models. The heater is equipped with a power cord. The heater is mounted in a threaded hole of the
engine cylinder block with the heating element immersed in engine coolant. The cord is attached to an engine compartment component with tie-straps.
The 5.9L diesel engine has the block heater located on the right side of the engine below the exhaust manifold next to the oil cooler (Fig. 9).
OPERATION
The heater warms the engine coolant providing easier engine starting and faster warm-up in low temperatures. Connecting the power cord to a
grounded 110-120 volt AC electrical outlet with a grounded three wire extension cord provides the electricity needed to heat the element.
